These "Hall of Fantasy" shows, originally broadcast on the Mutual Radio Network in 1953 were repackaged for syndication in the 1970s. They were aired on a local public radio station in 1978. This was the source for these recordings. They were recorded on reels and--since it was a public radio station--contain no news or commercials. These are slightly higher bitrate encodes than others available here, but, due to the age and quality of the source material, some don't sound as good as what is already available.
--Update--
I am reprocessing and re-uploading these in WAV.... stay tuned...
